MOORHEAD, Minn. (AP) — Officials often urge the public not to flush old prescription drugs because they pollute Minnesota’s waters.

But officials and environmental leaders concede the public has heard mixed messages over the years about what to do with pharmaceuticals and other compounds that can contaminate lakes and rivers. Minnesota Public Radio reports (http://bit.ly/165JtKR ) a new state grant program hopes to bring some clarity, helping people make the connection between the water they drink and the chemicals they put into the water.

Minnesota Department of Health project coordinator Michele Ross says the agency plans to distribute $100,000 a year to local groups. The money comes through the Minnesota Clean Water Fund. It’s not a lot of money, but Ross says local groups are often more efficient and effective at getting the message out.
